Description
The DB-3 Inline Duckbill Check Valve is Flanged Table E and is to be fitted inside your pipe to prevent back flow. This is an insertable rubber check valve. The end is secured in place by the flange. Suited to low back pressure applications. Size range starting from Pipe ID of 73.0mm. The pipe ID (internal diameter) must be advised at the time of requesting a quote or ordering. Choosing a Curved Bill or Straight Bill: - Curved Bill model - provides 50% more sealing area compared to the straight bill ended duckbill check valve, enabling a better tighter seal when debris are present. From 25cm head pressure to crack open the valve( curved end) this low head pressure does not fully open the valve, and for the valve to fully open, full flow is required with no back pressure. Does require a slightly higher cracking pressure to open the valve compared to the Straight Bill model. - Straight Bill model - opens with minimal cracking pressure, if debris are present there is a high chance it will effect sealing performance. Please advise the flange specification when ordering. Standard is AS2129 Table E. - Available in a range of flange specifications - contact us for a quote. - Available in a range of rubber materials such as Neoprene, NBR, EPDM, Viton - contact us for a quote. - 12 months warranty on manufacturing defects only.
